Apple said it did not give ID data to the FBI after a hacking group claimed to acquire the information from an FBI agent's computer.
"The FBI has not requested this information from Apple, nor have we provided it to the FBI or any organization," Apple spokeswoman Natalie Kerris told The Wall Street Journal.
When the hacker group Antisec claimed it acquired 12 million IDs, privacy concerns were raised. Developers use these IDs to track users across apps, the Journal said. Because developers also have databases of these IDs, organizations could obtain the data from app developers rather than directly from Apple.
On Tuesday, the FBI said the it had "no evidence indicating that an FBI laptop was compromised or that the FBI either sought or obtained the data," the Journal said.
New mobile software technologies will soon replace the use of these IDs, Apple said, so the company will ban its old ones.
